Specification of Letters Patent.

Patented Apr. 14, 1914.

- Application filed August 6, 1909. Serial No. 511,574.

To'all whom it may concern:

Be itknown that LVnnsrnn B. WHEELER, a citizen of the United States,residing at ashington, Districtjof Columbia, have invented new anduseful Improvements in Coin or Check Controlled Apparatus, of which thefollowing is a specification.

This invention relates to a coin or checkcontrolled apparatus operativein conjunction with diii'erent kinds of devices to permit a timed use ofthe latter, and it has been found particularly advantageous inconnection with an electrically controlled optical appliance such asthat disclosed by Patent No. 709.837, granted to me September 28,-

1902. The invention, however, is not limited to this particularapplication and essentially constitutes an improvement on theorganization of devices disclosed by Patent. 7 86,866 granted toineApril ll, 1905.

'The present iu-vcntionhas been devised to overcome disad vantages ofoperation of the mechanism disclosed by my Patent- 7 No. 786,866 andembodies features which are not only beneficial to the user, but also tothe person or persons having control or owning the apparatus,

The electricallv controlled optical appliance disposed by my Patent No.709,837 invalve: autol'natically operating shutters which are opened bythe closing of a circuit including the same to render the appliance orinstrument clear for practical service or vision or to shut off visionthrough the appliance o'r instrumentafter a certain period of use.

The present apparatus embodies a circuit which includes the magneticdevice or solenoid disclosed by the said Patent No. 709,837, and whichcircuit is normally broken at two points, one of which is closed by adirect operation of the user of the apparatus and the otherautomatically closed by a coin or check of a predetermined character.

The present improved apparatus also embodies mcans for. preventingfraudulent use of the same and also for insuring the 'oper ator in theuse of the optical appliance or device for a prescribed period of timein accordance with. the adjustment of the apparatus.

A preferred embodiment of the present invention is disclosed in theaccompanying drawings, and therein Figure l is a transverse verticalsection through the apparatus showing the latter in normal position anda coin or check as just having been inserted in the coin chute. F 2 is asimilar view in diagram illustrating the timing mechanism as having beenset by a direct operation of the pull rod by the user and also showingthe coin or check in a difi'erent position in the chute prior to itsliberation and further travel in the chute to close one set of thenormally open circuit elements, the remaining circuit elements nor mallyopen having been closed by the actuation of the timing mechanism. Fig. 3is a sectional elevationof the coin chute, showing the coin or check ashaving reached its final position prior to liberation and operating byits weight to close the norm-all y open circuit making elements adjacentthereto.

The apparatus represented has a casing 2 which may be of any desirableshape and material, and ordinarily consists of upper and lower chambers,the upper chamber receiving the coins or checks to bring about theaction of the apparatus and rendered accessible by a door which isusually locked and inaccessible except to authorized persons. Theoptical appliance, which is a pair of marine glasses 3, is adapted to behoused within. the lower chamber of the casing but may be ext-eriorlyexposed on a drop door or shelf d at least until the apparatus has beenset by the regularinsertion of a coin or check to render the saidglasses usable. The drop door or shelf dis used ber in which the glassesare disposed and said door may be locked to prevent access to theglasses within the lower chamber.

The working parts of the apparatus are mainly contained within the upperchamber, and the controlling element of the timing mechanism is disposedin a portion of the lower chamber which is divided by an intermediatepartition 5 so as to shut'ofi' the chamber for the glasses from' any ofthe working parts or prevent exposure of the said working parts andaccess thereto from the exterior when the glass chamber is opened.

for closing the lower compartment or chamn The apparatus iscomparatively light and may be readily transported from one point toanother, and the glasses 3 are secured by a suitable flexible cable oranalogous means 6 on the partition 7 between the upper and lowerchambers and forming a bottom for the upper chamber, the said cablebeing inserted through an opening 8 and having a portion thereof caughtover a hook 9 se cured on the partition or bottom 7 as clearly shown byFig. 1. In the said upper chamber of the casing is an inclined coin orcheck chute or run-way 10, the entering end of which coincides with aslot 11 in a face plate 12 on the front upper portion of that side ofthe casing 2 which stands toward the user, the extremlty of the chute orrunway 10 secured. to the side of the casing having a vertical extension13 which serves as a preliminary receiver for the coin or check. Betweenthe receiver and the main body of the chute or run-way below, a passage14 is provided, said passage being normally contracted to preventmovement therethrough of any coin until a certain operation ensues, by aslide or controller 15 movable on the upper edge of the chute or run-way10 and having its forward extremity 16 normally projected partiallyacross the passage lat, as shown by dotted and full lines in Figs. 1 and3. The slide or controller 15 is mounted in suitable guides 16 fixed onthe chute or run-way 10 and projecting laterally from one sideedge ofthe said slide or controller is a pin 17. The rear end of the slide orcontroller has an upwardly projecting forwardly inclined slotted head 18continually engaged by a pin or stud 19 projecting laterally from theupper goose neck or curved extremity 2O oi a coin or check liberatinglever 21. fulcrumed on the side of the chute or run-way as at 22, Theterminal of the goose-neck or curved extremity 20 is disposed close toone side of the chute or run way 10 and has a stop pin or stud 23projecting through and movable in an arcuate slot 24 in the said side ofthe chute or runway, the said pin or stud 23 extending far enough acrossthe interior of the chute or runway to stop the movement of a coin orcheck in the chute slightly in advance of a rear bottom outlet when thepin or stud 23 is down in normal position. The coin or check liberatinglever 21 has a rocking movement imparted thereto and the pin or stud 23rides freely upwardly and downwar ly in the arcuate slot 24. Fulcrumedon the side of the chute or run-way 10 opposite that over which thegoose-neck or curved extremity 20 of the lever 21 has movement anintermediate coin or check stop is applied and consists of anintermediately fulcrumed lever 25 having an upper slotted head 26 inwhich the pin or stud 17 has free movement and a lower stop pin orprojection 27 ex- -coin or check in the forward extremity tending intothe chute or run-way 10 through an elongated arcuate or segmental slot28, the stop being given suflicient throw or movement to clear the chuteor runway and having such timed actuation as to clear the chute orrun-way while the pin or stud 23 carried by the goose-neck or curvedextremity 20 or" the lever 21 is down in normal position. '1 heintermediate coin or check stop is normally elevated, as shown by Fig.1, and when the slide or controller 15 is actuated to clear the passage1a and permit the coin or check to pass into the main body of the chuteor runway 10 said intermediate stop is lowered and brought into theposition shown by Fig. 2 and holds the of the chute or run-way, thegoose-neck or curved extremity of the lever 21 being at this timeelevated, and when the intermediate stop is returned to normal positionby the release of the slide or controller 15 and the forward movement ofthe latter, the movement of the said intermediate stop is timed tomaintain control of the coin or check until the pin or stop 23 is downin its normal position and disposed to prevent liberation of the coin orcheck through the outlet 25 The mechanism cooperating with the chute orrunway 10 as just explained is actuated through the medium of a settingbar or rod 29 extending through the front side of the casing andprovided with a pull-head or knob 30. This setting bar or rod 29 ismounted in a sheath or tube 31 suitably slotted to expose a portionthereof, as indicated by dotted lines in Fig. 1: Projecting outwardlyfrom the rod or-bar 29 is a pin or stud 32 extending through a slot 33in the lower extremity of the coin or check liberating lever 29, andattached to the lower end of the latter lever and to the rear end of thecasing is a spring 34: which tends to restore all or' the parts tonormal position. When the rod or bar 29 is drawn outwardly the lowerextremity-of the lever 21 is moved in the same direction and the spring34; distended, and as soon-as the said bar or rod is released, thespring 34 exercises its retractile influence and instantly draws the baror rod rearu' ardly and restores the lever 21 to nor mal position. henthe lever 21 is moved outwardly with the bar or rod 29 as justexplained, the uppergooseneck or curved extremity 20 of the said leveris thrown rear-v wardly and draws in the same direction on the slide orcontroller 15 through the medium of the slotted head 18 and the pin orprojection 19,'and at the same time the intermediate stop 25 is movedfrom the position shown by Fig. 1 to that illustrated by Fig. 2 and thecoin or check inserted and preliminarily held in the extension 13 isper-' mitted to fall into the forward extremity of the chute or run-way10 in advance of the pin or projection 27 and the latter holds the saidcoin or check in the advance part of the chute until the bar or rod 29is released, and as before explained, the movement of the intermediatestop and of the goose-neck or curved extremity '20 of the lever 21 is sotimed that the intermediate stop will not release the coin or checkuntil the pin or stud 23 is fully lowered and ready to serve as a finalstop for the coin or check. By this means the operator or user isprotected as to the service of the coin or check which he has insertedand the electrical part of the apparatus is rendered active in clearingthe marine glasses for sighting purposes.

In the bottom of the chute or run-way 10 a weight-controlled orgravitating connector is mounted and consists of an intermediatelyfulcrumed lever 35,- the fulcrum being located nearer the frontextremity of the lever and thus dividing the latter into a rear long armand a forward short arm, the latter be ing shouldered as at 36 to engagea cone sponding shoulder 37 formed in the bottom of the chute or run-way10 to prevent de pression of the forward arm of said lever. Dependingfrom the forward arm of the lever is a contact hook 38 having its freeend disposed below and in position to engage a horizontal metalliccontact plate or member 39 carried by a rod 40 adjustable vertically ina binding post 41 to compensate for modifications in the movement of theweight-controlled or gravitating connector in accordance with the coinsor checks introduced into the chute or run-way to actuate the apparatus.A coin or check liberated by the intermediate stop moves through thechute or run-way over the lever 35 and when it reaches the rearextremity of the latter, or as it is approaching said extremity, thesaid lever is tilted downwardly and when the coin or check strikes thepin or stud 23 the rear extremity of the leveris fully depressedand thefree end of the hook 38 is held in contact with the plate or member 39,the parts being so proportioned that the coin or check will be preventedfrom moving farther toward the outlet 25* until the pin or stud 23 israised by a subsequent actuation of the lever 21 when another coin orcheck is insorted in the slotll and the rod or bar 29 pulled outwardlyto permit the said second coin or check to pass into and through ,themain portion of the chute or run-way, as hereinbefore explained, andwhen the said lever is so operated the coin or check which was firstinserted and has been held in the chute to maintain contact between theook 38 and plate or member 39 will be lib rated from the chute andfallto the partition or bottom 7.

The-hook 38 together with the lever 35 and plate or member 39constitutes a main circuit closer, and though the means for operatingthis circuit closer is illustrated in the form of a coin chute to showone practical application of the invention it is only necessary torender the more essential features of the invention operative andeffective in performing their desired function that the contact betweenthe hook 38 and the plate or member 39 be established and the tiltingaction of the lever 35 may be accomplished in any other manner. In otherwords the remaining features of the invention are not dependent upon thespecific form of coin chute for their operation so long as thecontacting elements consisting of the plate or member 39 and the hook 38are retained to constitute the main circuit closer and wherein the hookis movable with relation to the'plate or member. I The frame or supportfor the lever 35 and the latter will be connected to a source ofelectrical generation and the support for the plate or member 39 willalso be connected to the same source of electrical generation so thatthe hookand the plate or member serve as the terminals for the electriccircuit controlling the more essential features of the invention.

The timing mechanism in the improved apparatus is very simple anddiffersradically from that disclosed by my Patent No. 786,866, andpossesses many features of advantage, among which may be noted positiveaction due to the use of air as the controlling medium. This mechanismessentially comprises a bellows reservoir 42 having a suitable fiexiblebody with upper and lower heads 43 and 44 fixed to said body, the upperhead being provided with an interiorly located weight 45 at the center,a pin-hole 46 at one side of the center, and a tubular stem 47 risingfrom the upper side of the center and freely-movable througlian opening48 in the partition or bottom 7. The upper end ofthetube 47 has areduced opening 49 produced by an inwardly extending annular flange 50,and fixed to the upper end of the tube or tubular stem 47 is a contactdisk or plate 51 of metal. Freely movablein the tubular stem 47 is aweight 52 having a cord or chain 53 secured to the upper end thereof andtrained over a grooved pulley or sheave 54 held by an arm attached tothe rear of the casing. The opposite end of thecord 53 isattached to apin or stud 56 on the rod or bar 29 and is movable with the latter sothat'when the said rod or bar is drawn' out-' 'through the tubular stem47 until it strikes the flange 50 when the said stem and head 53,together with the body of the bellows reservoir, are drawn upwardly andcreate a suction in relation to the head 44. The head 44 has a centralinlet opening 57 in communication with a duct 58 opening through.

the rear side of the apparatus, the said head 44 being hollow as at 59and having communication through an opening 60 in a bottom plate 61 withthe duct 58. Over the opening 57 a yieldablc or elastic valve strip 62is secured, sufiicient play being given this strip to permit air toenter the reservoir when suction is exerted on the strip by the upwardmovement of the head 43. To insure the return to normal closing positionof the strip 62 a Weight 63 is fixed on the center thereof over theinlet opening 57 so that no air will be permitted to escape at thispoint but is all forced to pass out through the pin-hole or reducedescape aperture or opening 46. After the head 43 has been operated tofill the reservoir with air through the medium of the setting rod or bar29 and the said rod or bar is retracted within the apparatus, the weight52 descends in the tubular stem 47 and there is no resistance to thegradual collapse of the air reservoir. This collapse ensues verygradually as the air escapes slowly through the pin-hole or opening 46,and as the quantity of air gradually lessens in the air reservoir thehead 43 settles or gravitates toward the head 44, drawing the tubularstem and disk 51 downwardly therewith, and as will be more fullyhereinafter explained the said disk 51 by its depression or at thetermination of a predetermined interval of time will break an electriccircuit and render the marine glasses inoperative for sighting purposesby closing the shutter means thereof. Two metal contact arms 64 and 65are disposed to operate with the disk or plate 51, both arms havinginner bent terminals 66 and each fulcrumed on a post the arm 64 beingpivotally supported by a post 67 and having a spring 68 attached theretowhich tends to draw the said arm 64 downwardly and maintain the bent end66 thereof in contact with the disk 51, the said arm 64 .being unlimitedin its downward movement and thereby always held in contact with thesaid disk. The arm 65 is fulcrumed on a post 69 having a laterallyprojecting head 70 in which is mounted a set-screw 71 freely adjustableto engage the adjacent end of the arm 65 to limit the downward movementof the latter and cause the free end thereof or'the bent end 66 incontact with the disk 51 to break contact with said disk after a certaininterval of time during the descent of the disk and tubular stem 47 andthereby break the electric circuit in which the post 69 and arm 65 areincluded.

The electric current is derived preferably from a dry cell 72,though'other means may be used, and said cell is disposed in a metallicsocket 73 depending from the intermediate partition of bottom 7 of theupper chamber. l/Vithin the lower ,extremlty of the socket 73 a spring74 is mounted and makes an electric contact with one pole of the cellwhen the latter is pressed downwardly thereagainst and by this means anelectric connection is set up between the cell and socket. Adjacent tothe upper extremity of the socket 7 3 a guide rod or post 7 5 rises fromthe partition or bottom 7 and thereon a pressure arm 7 6 is'slidinglymounted and adapted to be held in fixed adjustment by a set-screw 77engaging a portion of the arm and impinging against the rod or post 75.The free end of the pressure arm 76 is provided with a contact plate 78which is caused to engage with the remaining pole of the cell at the topof the latter, the said arm 7 6 also having the function of holding. thecell down in place in the socket and ob viating movement of the saidcell during transportation of the apparatus, for instance. The cell 7 2may be readily removed and revivified when occasion requires or replaced by another similar device simply by loosening the arm 76 andelevating said arm on the rod or post and without requiring detachmentor attachment of electrical connections, such as wires.

As disclosed in my Patent No. 709,837, the cable or cord 6 incloses twowires or electrical connections to establish a circuit with the magneticdevice or solenoid controlling the shutters, and these wires areattached to metallic terminals 7 9 and 80 having suitable bindingscrews, as illustrated by Fig. 2. A wire 81 is attached to the terminal79 and to the binding post 41 adjustably supporting the contact plate ormember 39 through the medium of the rod or post 40. To the terminal 80 awire 82 is attached and also to the base of the rod or post 7 5, andfrom the socket 73 awire 83 runs to the base of the post 69 supportingthe arm 65. From the base of the post 67 on which the arm 64 is mounteda wire 84 runs to the upper portion of the extension 13 of the chuteorrun-way 10, as clearly shown by Fig. 2, and as all the parts thusconnected are of metal a reliable metallic circuit will be establishedwhen the hook 38 is in contact with the disk or member and both arms 64and 65 are in contact with the disk or member 51.

The operation of the apparatus will be readily understood from theforegoing description, but to enumerate the several actuations from theinsertion of the coin or check to the final automatic closure of theshutter means in the marine glasses, the procedure and operation of theseveral elements are as follows: The person desiring to use the glassesinserts a coin or check in the coin slot 11 and the said coin or checkis retained in the extension 13 by the forward end of the slide orcontroller 15 normally contracting the passage 14, as shown by Fig. 1.The user or operator then pulls the rod or bar 29 fully outwardlyagainst the resistance of the spring 34 and by the operation of theintermediate step 25, slide 15 and lever 21 as hereinbefore explainedthe coin or check is permitted to descend into the outer extremity otthe chute or run-way 10, as shown by Fig. 2, and at thesame time thecord 53 has had suflicient stress exerted thereon to cause the weight 52to pull the tubular stem 47 and head 43 of the bellows reservoir 42upwardly and charge the said reservoir with 'a quantity of air. When thetubular stem is thus pulled upwardly the bent ends (36 of the arms 64and 65 are brought into contact with the disk 51, the said arms 64 and65 being elevated against the resistance of the springs 68 and 65, thelatter spring being attached to the arm 65 in a manner similar to theattachment of the spring 68 to the arm '64. The coin or check remains inthe outer or forward extremity of the chute or run-way 10 so long as therod or bar 29 is held drawn outwardly as shown by Fig. 2. When the baror. rod 29 is released the spring 34 attached to the lower end of thelever '21 quickly restores said rod or bar to normal position, and theupper goose-neck or curved extremity 20 of the lever 21 is-caused tomove downwardly, the slide or controller ,15 simultaneously shiftedforwardly to again constrict the passage or throat 14, and theintermediate stop embodying the lever 25 thrown around to release thecoin or check and the latter then travels over the weightcontrolled orgravitating connector or lever 35 and causesfthe hook 38 to engage thecontact plate or member 39vand completes the circuit, which will be fromthe metallic terminal 80 through wire 82 to the base of the post 7 5.,through the cell 72, spring 74, metallic socket 73, by wire 83 to thebase of the post 69 and arm 65 to disk 51, arm 64 and post 67 by wire 84to the upper portion of the extension 13 of the chute or run-way 10 andthrough the latter by the hook 38 to plate 39 and rod 40 to bindingpost41 and .by wire 81 to the remaining terminal 79. The moment thiscircuit is completed the magnetic device or solenoid in the marlneglasses will be energized to operate the shut ter means to clear saidglasses for sight ng purposes and the user is at liberty v to viewobjects and scenes through the glasses.

During the use of the glasses the check or coin will be held in thechute or run-way 10, as shown by Fig. 3, and the contact between thehook 38 and the plate 39 will be constantly and positivelymaintainedthrough the medium pf the coin or- -check holding the weight-controlledconnector or lever 35 in depressed position. The head 43, tubular stem47 and disk 51 will immediately start to gradually lower by the escapeof the air through the pin-hole or openlng -46, and as the diskSligradually falls the bent ends 66 of both arms 64 and 65 will followin contact therewith .for a certain length of time or until thefulcrumed extremity of the arm 65 engages the end of the screw 71, whenthe contact between the end 6 of the arm 65 and the disk 51 will bebroken by a continued descent of the said disk and the circuit likewisesimultaneously broken. As soon as the circuit is broken by the"operation just explained the magnetic device or solenoid in the marineglasses is deinergized and the shutter means will be instantly operatedto close the said glasses and thus prevent further use of the latteruntil another'coin or check is inserted in the slot 11 and the sameoperation pursued. The coin or check which is utilized to operate .themechanism and occupying the position illustrated by Fig, 3 remalns inthe chute or run-way 10 until a subsequent coin or check is inserted inthe slot 11 and eX- tension 13 of the said, chute and the first usedcoin or check is liberated only when the rod or bar 29 is drawnoutwardly to give entrance to asubsequent coin or check into the'ehuteor run-way 10, and as soon as the coin or check first introduced isliberated from the chute or run-way the weight is relieved from theconnector or lever 35 prior to engagement with the said connector orlever of the second coin or check and the contact between the hook 38and the plate or member 39 is immediately broken and will not berestored until the second coin or check is liberated by the intermediatestep or lever 25, and travels over the connector or lever 35 and reachesthe position shown by Fig. 3. This particular operation has been devisedto prevent fraudulent or repeated use of the apparatus by theintroduction or through the medium of a single coin or check and also toinsure the user in the operation of the glasses. If an attempt is madeto use the apparatus without properly inserting a coin or check andwhile a pre-,

yiously introduced coin or check remains in the chute or run-way 10 andoccupies the position shown by Fig. 3, such use is defeated the momentthe bar or rod 29 is drawn outwardly, as the first introduced coin orcheck will be liberated and fall through the outlet 25 into the upperchamber of the apparatus and at the same timebreak the contact between.the hook 38 and the plate or member 39 and as a consequence the shuttercans in the marine glasses will remain :losed. The user or operatorregularly inserting a coin or check-is protected or insured as to theoperation of the shutter means in the marine glasses to clear'the latterby the intermediate stop or lever 25. But. for this intermediate stop acoin or check would pass fully through and out from the chute or run-way10 the instant the rod or bar 29 was drawn outwardly andv the noscircuit would not be completed and hence the shutter means in the marineglasses would remain closed. By following instructions or explanationsas to the use of the apparatus and which will be disposed in aconspicuous position on the front of the easing, an operator willreadily ascertain that by applying the glasses to the eyes afterinserting a coin or check the said glasses will be cleared for vision bya single outward pull and release of the rod or bar 29, and by followingthe simple instructions loss of the coin or check without use of theglasses will be prevented,

By way of example and explanation, marine glasses have been hereinbeforeparticularly referred to as rendered usable by the actuation of theapparatus, but it will be understood that any other devices might besubstituted for the marine glasses with similar operative andinoperative results.

The electric current generator or cell 72 and the electric circuit areshown included in the equipment of the apparatus to render thecomplement of the latter complete for portable purposes. The apparatusmay, however, be used in theaters, lecture halls and the like andcontrol the use of optical glasses, and under these conditions thesupply or" electric current may be located at a distance from theseveral apparatuses and under the control of a suitable switch-board,

This particular application would notinvolve a modification of theapparatus as the circuit would be the same in each glass controllingapparatus and the timing mechanism would similarly come into play aswell as the coin chute and other devices controlling the circuit so asto make and break the latter, as hereinbefore fully explained.
